. 'i Claims.

This invention relates to wall construction for metallic buildings. Among the objects of this invention are: To provide a comparatively inexpensive metallic wall construction; to provide a wall construction which effectively insulates Athe interior of the buildingv against heat and cold; to provide a simple leak-proof joint for the outside sheathing thereof; to provide simple and easily assembled tying connections betweenthe inner and outer members ofthe walls; to

provide a simple and substantial corner construction for connecting the walls; to provide means for permitting expansion and contraction Vat all joints; to provide air ducts in the walls Fig. 1 is a fragmental, vertical, cross section taken through vthe wall and iioor of a metal building containing a simple embodimenty of the present invention;

Fig. 2 is a horizontal section taken throug one of the corner portions of the building; V

Fig. 3 is a detail, fragmental, vertical section, illustrating the form of jointused between the sheets of the outside sheathing; v

Fig. 4 is a fragmental, vertical section through the corner post or column taken on the line 4-4 of Fig. 2; and y Fig. 5 is a detail, fragmental, horizontal section through one of the joints between the outside sheathing and the corner post or column.

Referring to said drawing, which is merely illustrative of one form of the invention, the reference character I0, designates the foundation wall of the building, which may be composed of concrete, brick or the like. As shown, the foundation wall may have an oiset or shouldered part Il, to receive and support floorgirders, one

of which is shown at I2.

'Extending around the top of the foundation 'wall is a sheet metal-sill plate I3, usually composed of several sections, depending on the length and breadth of the building, and said (Cl. 18S-34) sill plate I3 is bent .along' longitudinal lines to provide a top plate Il, from the outer edge of which rises an upstanding flange I5, and from the inner edge of which depends a vertical facing I6, which terminates in a horizontal flange I1, that lies upon-the offset part Il of the foundation wall. 'Ihe flanges I5 terminate at the corner parts of the building. o

suitably spaced along the foundation wall and rising from the sill plate are studs, one of which is seen at I8, `desirably formed of sheet metal, folded and doubled upon itself to` provide a T-shaped stud. Angle plates I9, spotwelded or otherwise rigidly secured to the ,lower ends of the studs'are provided for bolting Vthe studs to the sill plate as by boltsand nuts 4I. Desirably the bolts and nuts are formed of some noncorrosive metal. The upper ends of the studs are connected by structural metal bars (not shown), thereby providing a rigid skeleton frame work for supporting the outside sheathing 29, and the inner walls dit. Desirably the sheathing is composed of horizontally extending metal sheets 2l, 22, placed one above the other about the building, except at the places where the door and window openings occur, and novel joints 9, are provided between the adjacent sheets, which will now be described.

Referring to Fig. 3, the upper sheet 2i (of any adjacent two sheets) is folded upward as at 23, along a longitudinal line adjacent its lower edge Ato provide a flange 2t, and then folded downward as at -25 to provide a down turned ange 26, spaced away from the flangeV 2d sufiiciently to receive'an oset flange 2 1, of the lower sheet 22, and the upstanding oset tongue 28, of a supporting bracket 29. ItA will be observed that the outer facesof the sheets 2|, 22, are flush with eachother. This is accomplished by offsetting inwardly the upper edge portion 21 of each sheet, a distance equal to the two thick- Ariesses of metal formed by the sheet 2l above it, and its iiange 24.

The brackets 29 are spotwelded or otherwise rigidly secured to the studs in position to have their onset tongues 28 enter the grooves between the onset iiange 21 of the lower sheet and the down turned flange 26 of the upper sheet. The brackets 29 are located on the studs atv every joint between the sheets andserve to support the sheets as well as to tie them' to the struts and hold them ush with each other.

The lower edge portions of the bottom sheets vproject. down somewhat below the top of the foundation wall (see Fig. 1), and have strips metal 33 spotwelded to their inner faces, thatarebentdownovertheupstandingflanges I of the sill plate, thereby securely tying the lower edges of the bottom sheets to the founda-l s tion wall.

At the several corners of the building, hollow corner posts or columns 3l (see Fig 2) are provided for tying the walls together. Desirabiy each corner post comprises two upright metal sheets 32, 33, bent along longitudinal lines midway between their side edges as at 34 to provide the right angled outer sides 35, and the right angled inner sides 35, of a square post or column. The upright edge portions of the sheet which forms the outer sides 35 are doubled upon themselves to provide flanges 31, spaced sumciently from the sides 35, to receive outwardly bent flanges 38 that are formed on the edges of the sheet which forms the inner sides 35 (see Y 2o Fig. 5). The two bent-up sheets .32, 33, are

spotwelded or otherwise welded together at the joints between them, thereby providing an extremely rigid and substantial corner post. The inner sides 33 of the corner post rest on the sill plate, but the outer sides 35 project below the sill plate and overhang the upper edge portion of the foundation wall at the corner.

Angle irons 39, are spotwelded or otherwise secured to the lower edge portions of the inner 3o sides 36 of the posts and are fastened to the foundation wall by bolts 4I, that are embedded in the concrete and projected up through the] sill plate I3, and through the angle irons 33. and have nutsthreaded upon their upper ends which are screwed down upon the angle irons. A square flanged foot plate 40 is spotwelded to the inner faces of the post, adjacent its bottom, and rests upon the sill plate (see Fig. 4).

Flanged angle iron braces 43 are spotwelded 40 to the inner faces of the sides 35 of the post' to strengthen and reinforce the' post at its outer corner. These angle iron braces are suitably spaced apart along the length of the post.

The inner walls 44 of the building are de- 45 sirably composed of sheets or slabs of heat nonconducting material, of which there are many kinds on the market, these employing asbestos in their composition being preferred. They are usually in the form of rectangularv sheets or slabs, and for the purposes of this specification,

may be termed wall boards. wall board designated by 45, rests in a vgroove formedI i-n the top of a sheet metal base board 46. At the horizontal joints between upper and lower wall boards, they are held ush with each other by H shaped beads 41, desirably formed of strips of sheet metal bent upon themselves, as shown, to form upright iianges 43, connected by horizontal Webs 49. One of the upright iianges of the bead is provided with down-turned tongues 48" hooked upon the here-y inafter described braces 50 carried by the studs; The beads carry the wall boards flush with each other and effectively tie them together and provide decorative strips running horizontally around the inner faces of the walls of the building. The beads may, of course, be continued around the partitions (not shown) as well as around the walls.

'I'he wall boards are also tied to the studs I3 by other braces 50 similar to the braces 50 above referred to. All of said braces are desirably formed of strips of sheet metal folded upon themselves to provide a Tv shaped brace (see Fig. 2) having legs 5I, that straddle and are The lowermost spotwelded or otherwise secured to the studs Il. The braces are spaced at intervals' along the lengthofthestudsandextendtotheinner faces of the wall boards wherethe head portion; 52 of each brace is slotted vertically to receivel 5 an offset down-turned tongue 53 of a/bracket 54, screwed, riveted or otherwise securely fw tened to the adjacent face of the wall board. In fastening a wall board 44 to the studs I3, it is lifted to bring the tongues 53 above the upper 1u edges of lthe T braces 5I and then lowered, bringing the tongues down into the slots in the heads. thereof. When thus fastened, thesheathing and wall boards are rigidly tied together, thus providing a very rugged, rigid and substan- 15 tial wall structure.

At. the corners 'of the. building the'outside sheathing and the wall boards join with the. corner posts. These joints will now be described: 20

spotwelded or otherwise secured to the inner sides 35 of the corner post," at spaced intervals along its length, are flanged metal strips 55,'tli`e outer iianges 55 of which are spaced from the flanges 31 of the outer sides 35 of the post, a 25 distance equal .to the thickness of the outside sheathing tcl receive the adjacent edges thereof. 'Ihe flanged strips 55 and anges 31 of the corner posts hold the edges of the outside sheathing iirmly in place and provide for expansion and 30 contraction thereof.

Flanges 51 disposed at right angles to each other are spotwelded or otherwise secured to 'the inside corner 34 of the corner post. These iianges parallel the inner iianges 56 of the flanged 35 strips 55, and are spaced therefrom a distance equal to the thickness of the wall board and receive the end edges thereof between them, thus providing the connection between the wall boards vand corner, and providing for 4expansion and 40 l.or composed of corrugated metal are laid o'n the foundation walls and on the girders I2. On 50 these slabs is placed the ooring proper 60, which may be of any appropriate form. The base boards 45, are detachable and as shown are screwed to bent-up metal strips 6I, that project down behind the ooring. 55 Hot or cold air conduits 62, may extend completely around the walls within the space between the struts -I8, and the wall boards, and may be provided with outlets (not shown) at the various rooms of the building. Flues (not shown) may 60 lead from the usual heating plant or air conditioning plant to the conduits, whereby hot air or conditioned air may be conducted through the conduits and discharged into the rooms. As is customary, a return nue may lead back to the 65 furnace from some room of the building. Obviously, any other approved form of heating sys.. tem may be employed.

' To more effectively insulate the interior of the building from heat or cold all the available l70 spaces between the outside sheathing and wall boards may be filled with mineral wool or other thermotic insulating material.

Door and window openings may be provided at any desired places, and the exposed faces-15 assembled at the place where the building is to t be erected. l More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described,.but intend, in the following claims, to point out all of the invention disclosed herein.
